Underwater Pile Cutting

Overview of Under Water Pile Cutting by Abrasive Water Jet

RGL has for many years led the field in abrasive water jet cutting but over recent years we have developed the specialty of cutting hollow steel piles underwater from the inside out. This technology has been successfully deployed in a diverse range environments such as rivers, estuary’s, offshore and on land. To date, we have successfully cut off “piles”, “met masts” and “wind turbine supporting monopiles” ranging in diameter from over 4 meters right down to 300mm and many in between.

Our remote control internal pile cutting system enables us to cut off piles below ground or sea bed level. This removes the need for divers. Typically, we would operate from pontoons or jack-up barges but each situation is different and we adapt accordingly.

Due to the huge variations in sizes and operating conditions, RGL’s in house design and fabrication teams are able to manufacture bespoke rigs and associate equipment to suit most requirements.

Please see the schematic below which outlines RGL’s typical pile cutting process from dredging, proving and cutting.
